2- 10foot 1 1/4 inch black iron pipe
1- 10 foot 1 inch black iron pipe

2- #40 Roller Chain Carnell Sales, Inc. 40-1R
5- 1 1/4 pvc couplers cut long ways
5- 1 inch pvc coupler cut long ways
image.jpg
my first attempt at holding 1 inch pipe down with a 10 foot 2x4 did not work
I tried to make bearings out of pvc fittings and polyurethane blue
the first methond with 2x4 only worked for small widths
3/4" Shaft Coup with Keyway ,10 Tooth Sprocket for #40 chain
roller only worked for small widhths
I wanted to create a small radius on bottom
image.jpg
hand bent bottom to make small radius
image.jpg
image.jpg
initial bend started by pinching metal down with pipes and using a length of wood to start bend

without the use of a center clamp
difference with and without center clamping
center clamp used to pinch 1 inch pipe against the two 1 1/4 pipes
center clamp released and applied as metal is rolled
center clamp released rolled and the center clamp applied

tiny index between application of center clamp
roll, center clamp, center release, roll - repeat
the 2x4 end clamps will move during the rotation
center clamp is needed since the 1 inch deflects in the center
both ends are clamped. The 2x4 clamp will move as pipes are rotated
